Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to an air duct component, a storage device and a refrigeration equipment. Background Technology

[0002] In refrigeration equipment, multiple storage drawers are usually arranged to achieve flexible storage and cleaning partitions, such as fresh food drawers and freezer drawers. In order to meet different storage needs, independent cold air vents can be arranged in the storage drawers.

[0003] However, because the air vents in the storage drawer are located at the back of the drawer, there is ample cold air at the back and less cold air at the front, resulting in uneven temperatures inside the drawer and affecting the preservation or freezing of food inside. Utility Model Content

[0004] This invention provides an air duct component, a storage device, and a refrigeration equipment, which can solve the problem of uneven temperature inside the storage drawer, affecting the preservation or freezing effect of the food inside the drawer.

[0005] The technical solution is as follows:

[0006] On one hand, an air duct assembly is provided, the air duct assembly comprising: an air duct plate body;

[0007] The air duct plate body includes an air inlet, an air guide channel, at least one first air outlet and at least one second air outlet;

[0008] The air inlet is located on the first side of the air duct plate body, and the at least one first air outlet is located on the second side of the air duct plate body, and the at least one first air outlet faces a direction away from the air inlet, wherein the first side and the second side are arranged opposite to each other along a first direction;

[0009] The at least one second air outlet is located on the duct plate body between the air inlet and the at least one first air outlet;

[0010] The air guide channel is located within the air duct plate body and is connected to the air inlet, the at least one first air outlet, and the at least one second air outlet, respectively.

[0011] In this embodiment, the air duct assembly has an air inlet on the first side of the air duct plate body and a first air outlet on the opposite second side. A second air outlet is also arranged in the area between the air inlet and the first air outlet. The first air outlet can deliver cold air to the area on the farthest side, and the first air outlet is facing away from the air inlet. The cold air can continue to be delivered to a farther place under the action of delivery pressure. The area between the first air outlet and the air inlet is delivered cold air using the second air outlet. The first and second air outlets can achieve large-scale and long-span cold air delivery, and the uniformity of cold air delivery is better, and the temperature in the air delivery area is more balanced. When the air duct plate body is applied to a storage drawer, it can deliver cold air to the front and middle rear sides of the storage drawer simultaneously. The cold air distribution inside the storage drawer is even, which is beneficial to improving the storage effect of the storage drawer for food.

[0012] In some possible implementations, there are multiple first air outlets, and the multiple first air outlets are arranged at intervals along a second direction on the second side, the second direction being perpendicular to the first direction;

[0013] The area of ​​the first air outlet located in the middle of the second side is larger than the area of ​​the first air outlet located at the edge of the second side.

[0014] In order to increase the air volume on the first side of the air duct plate body, there are multiple first air outlets, which are arranged at intervals along a second direction perpendicular to the first direction, so that the total air volume of the first air outlets can be guaranteed.

[0015] Furthermore, in order to ensure sufficient airflow in the middle of the first side of the air duct plate, the area of ​​the first air outlet in the middle position is larger, while the area of ​​the first air outlet at the edge position is smaller, resulting in a larger volume of cold air output in the middle of the first side.

[0016] In some possible implementations, the at least one second air outlet is located on the first surface of the air duct plate body, the at least one first air outlet is inclined toward the first surface, and the angle between the air outlet axis of the at least one first air outlet and the first surface is α, wherein the value of α is in the range of 20°-40°.

[0017] In this embodiment, the air outlet axis of the first air outlet is tilted at a certain angle so that the cold air delivered by the first air outlet blows directly to the corresponding storage area, which can avoid the first air outlet blowing directly onto the door or door seal structure, causing condensation to appear on the outer surface of the door or door seal structure.

[0018] In some possible implementations, there are multiple second air outlets, which are spaced apart and arranged on the first surface of the air duct plate body.

[0019] The area of ​​the second air outlet located in the middle of the first surface is larger than the area of ​​the second air outlet located at the edge of the first surface.

[0020] In order to increase the air volume in the area corresponding to the first surface of the air duct plate body, there are multiple second air outlets, which are arranged at intervals along the first surface, so that the total air volume of the second air outlets can be guaranteed.

[0021] Furthermore, in order to ensure sufficient airflow in the middle of the first surface of the air duct plate, the area of ​​the second air outlet in the middle position is larger, while the area of ​​the second air outlet at the edge position is smaller, resulting in a larger volume of cold air output in the middle position of the first surface.

[0022] In some possible implementations, the air duct includes a main air duct, at least one first branch air duct, and at least one second branch air duct;

[0023] The main air duct extends along the first direction, one end of the main air duct facing the first side is connected to the air inlet, and the other end of the main air duct facing the second side is connected to the at least one first branch air duct. The at least one first branch air duct is respectively connected to the at least one first air outlet.

[0024] The at least one second branch air duct is connected between the two ends of the main air duct and is respectively connected to the at least one second air outlet.

[0025] With the above arrangement, the cold air input from the air inlet can enter different first and second branch air ducts along the main air duct. The cold air entering the first branch air duct can be blown out through the first air outlet, and the cold air entering the second branch air duct can be blown out through the second air outlet.

[0026] In some possible implementations, when there are multiple first air outlets, the multiple first air outlets are divided into two groups, and the two groups of first air outlets are located on both sides of the main air duct along the second direction, and each group of first air outlets is connected to the main air duct through a first branch air duct.

[0027] And / or,

[0028] When there are multiple second air outlets, the multiple second air outlets are divided into at least two groups, and the first air outlets of the at least two groups are located on both sides of the main air duct along the second direction, and each group of second air outlets is connected to the main air duct through a second branch air duct.

[0029] With the above arrangement, the two sets of first air outlets can be connected to the main air duct through two first branch air ducts respectively. Furthermore, the two sets of first air outlets are arranged on both sides of the main air duct, ensuring that multiple first air outlets are spaced apart along the second direction while guaranteeing that each set of first air outlets receives sufficient airflow. Similarly, the two sets of second air outlets can be connected to the main air duct through two second branch air ducts respectively. Moreover, the two sets of second air outlets are arranged on both sides of the main air duct, ensuring that multiple second air outlets are spaced apart along the second direction while guaranteeing that each set of second air outlets receives sufficient airflow.

[0030] In some possible implementations, the main air duct is provided with diversion ribs, which are arranged along the first direction and located in the middle of the main air duct along the second direction.

[0031] In order to ensure that the cold air in the main air duct can be evenly distributed to each first branch air duct and each second branch air duct, a diversion rib is arranged in the middle of the main air duct along the second direction to divide the cold air into two streams, and the two streams of cold air flow into the corresponding first branch air duct and the corresponding second branch air duct respectively.

[0032] In some possible implementations, when the plurality of second air outlets are divided into at least two groups and respectively arranged on both sides of the main air duct along the second direction, the number of second branch air ducts is at least two.

[0033] One end of each of the second branch air ducts is connected to the main air duct, and the other end extends away from the main air duct along the second direction and tilts towards the second side, so that the main air duct and at least two second branch air ducts are arranged in a fishbone shape.

[0034] With the above arrangement, each second branch air duct has an inclined angle facing the direction of cold air entry, which can improve the efficiency of cold air entering the second branch air duct, thereby improving the air delivery efficiency of the second air outlet.

[0035] In some possible implementations, the duct plate body includes a thick plate portion and a thin plate portion, with the first side and the second side located on opposite sides of the thick plate portion along the first direction;

[0036] The at least one second air outlet is located on the first surface of the thick plate portion; the thin plate portion is connected to the second side and is located on the side of the at least one first air outlet facing away from the first surface.

[0037] In this embodiment, a thin plate portion is attached to the first side of the thick plate portion, and a stepped surface is formed at the structural position of the thick plate portion and the thin plate portion. The stepped surface has a surface perpendicular to the first direction, which just meets the arrangement requirements of the first air outlet. In this way, the arrangement difficulty of the first air outlet is greatly reduced.

[0038] On the other hand, a storage device is provided, the storage device comprising: the air duct assembly described in this utility model, as well as a housing assembly and a storage drawer;

[0039] The housing assembly has a storage compartment, and the storage drawer is movably inserted into the storage compartment;

[0040] The air duct assembly is located on the top partition of the housing assembly, with the first direction parallel to the direction of movement of the storage drawer, and the second side facing the opening of the storage compartment.

[0041] The storage device in this embodiment uses the air duct assembly of this utility model, and has all the beneficial technical effects of all embodiments herein. The air duct plate body can simultaneously deliver cold air to the front and rear sides of the storage compartment, and the cold air distribution inside the storage compartment is even, which is conducive to improving the storage effect of the storage device on food.

[0042] In some possible implementations, the air duct plate body is located on the outer side of the top partition, and the top partition is provided with a third air outlet corresponding to the first air outlet and a fourth air outlet corresponding to the second air outlet.

[0043] The rear partition of the housing assembly is provided with an air inlet channel corresponding to the air inlet, and a return air channel connecting the storage compartment.

[0068] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0070] Unless otherwise defined, all technical terms used in the embodiments of this utility model have the same meaning as commonly understood by those skilled in the art.

[0071] Storage drawers in refrigeration equipment usually need to be equipped with independent cold air vents so that the independent space inside the storage drawer can form a storage environment that meets different needs, such as preservation, freezing, and humidification.

[0072] However, in some refrigeration units, the front area of ​​the storage drawer lacks sufficient space for air vents, creating a vacuum zone for cold air delivery. This results in a higher temperature in the front area compared to the rear of the drawer. Furthermore, storage drawers typically open by pulling forward, and the drawer door is sealed by a door seal, which has relatively poor insulation. The front area, being close to the door seal, inevitably experiences heat leakage, further exacerbating the temperature difference between the front and rear of the drawer. For all these reasons, the temperature uniformity inside the storage drawer is poor, affecting the preservation of food.

[0073] Therefore, this utility model provides an air duct assembly that can simultaneously deliver cold air to the front and rear sides of the storage drawer, resulting in a balanced distribution of cold air inside the storage drawer, which is beneficial to improving the storage effect of the storage drawer on food.

[0074] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0075] On the one hand, combined with Figure 1 and Figure 2 As shown, this embodiment provides an air duct assembly, which includes: an air duct plate body 1.

[0076] The air duct plate body 1 includes an air inlet 11, an air guide channel 12, at least one first air outlet 13, and at least one second air outlet 14. The air inlet 11 is located on a first side 10a of the air duct plate body 1, and at least one first air outlet 13 is located on a second side 10b of the air duct plate body 1, with the at least one first air outlet 13 facing away from the air inlet 11. The first side 10a and the second side 10b are arranged opposite to each other along a first direction A. At least one second air outlet 14 is located on the air duct plate body 1 between the air inlet 11 and the at least one first air outlet 13. The air guide channel 12 is located inside the air duct plate body 1 and is connected to the air inlet 11, the at least one first air outlet 13, and the at least one second air outlet 14, respectively.

[0077] In this embodiment, the air duct assembly has an air inlet 11 arranged on the first side 10a of the air duct plate body 1, and a first air outlet 13 arranged on the opposite second side 10b. A second air outlet 14 is also arranged in the area between the air inlet 11 and the first air outlet 13. The first air outlet 13 can be used to deliver cold air to the area where the farthest first side 10a is located, and the first air outlet 13 is facing away from the air inlet 11. The cold air can continue to be delivered to a farther place under the action of delivery pressure. The area between the first air outlet 13 and the air inlet 11 is delivered cold air using the second air outlet 14. The first air outlet 13 and the second air outlet 14 can realize the delivery of cold air over a large range and a long span, and the uniformity of the cold air delivery is better, and the temperature in the air delivery area is more balanced.

[0078] When the air duct plate 1 is applied to the storage drawer 3, it can simultaneously deliver cold air to the front and middle rear sides of the storage drawer 3, and the cold air distribution inside the storage drawer 3 is balanced, which is conducive to improving the storage effect of the storage drawer 3 on food.

[0079] In some examples, the number of first air outlets 13 can be one, two, three, etc. The number of second air outlets 14 can also be one, two, three, etc.

[0080] In some possible implementations, the air inlet 11 is connected to an air supply device, which can be a refrigeration device in the refrigeration equipment, such as a cold air circulation system composed of a compressor, condenser, expansion valve, evaporator and fan. Air releases heat in the evaporator, and the temperature drops to form cold air. Driven by the fan, the air enters the air inlet 11 and is then delivered to each first air outlet 13 and each second air outlet 14 through the air guide channel 12 to achieve cooling of the target area.

[0081] For example, the total air volume of the first air outlet 13 and the second air outlet 14 can be controlled by the speed of the fan, by the damper arranged between the air inlet 11 and the fan, or by the working status of the compressor and the expansion valve.

[0082] Combination Figure 3 As shown, in some possible implementations, there are multiple first air outlets 13, and the multiple first air outlets 13 are arranged at intervals along the second direction B on the second side 10b, the second direction B being perpendicular to the first direction A.

[0083] The area of ​​the first air outlet 13 located in the middle of the second side 10b is larger than the area of ​​the first air outlet 13 located at the edge of the second side 10b.

[0084] In order to increase the air volume of the first side 10a of the air duct plate body 1, there are multiple first air outlets 13, which are arranged at intervals along the second direction B perpendicular to the first direction A, so that the total air volume of the first air outlets 13 can be guaranteed.

[0085] Furthermore, in order to ensure sufficient airflow in the middle of the first side 10a of the air duct plate body 1, the area of ​​the first air outlet 13 in the middle position is larger, and the area of ​​the first air outlet 13 at the edge position is smaller, resulting in a larger airflow of cold air in the middle of the first side 10a.

[0086] Combination Figure 4 As shown, in some possible embodiments, at least one second air outlet 14 is located on the first surface 10c of the air duct plate body 1, at least one first air outlet 13 is inclined toward the first surface 10c, and the angle between the air outlet axis 13a of at least one first air outlet 13 and the first surface 10c is α, wherein the value of α is in the range of 20°-40°.

[0087] In the storage device scenario, when the air duct plate body 1 is in use, the first air outlet 13 may face the door or door seal structure of the compartment. Since the cold air delivered by the first air outlet 13 is at a low temperature, blowing directly onto the door or door seal structure will cause the temperature of the door or door seal structure to be too low, which will cause condensation to appear on the outer surface of the door or door seal structure.

[0088] Therefore, in this embodiment, the air outlet axis 13a of the first air outlet 13 is tilted at a certain angle so that the cold air delivered by the first air outlet 13 is directly blown towards the corresponding storage area.

[0089] In some possible implementations, the angle α between the air outlet axis 13a of the first air outlet 13 and the first surface 10c is, for example, 20°, 25°, 30°, 35°, 40°, etc.

[0090] Combination Figure 5 As shown, in some possible embodiments, the first air outlet 13 includes a first air outlet wall 131 and a second air outlet wall 132. The first air outlet wall 131 and the second air outlet wall 132 are arranged at intervals along a direction perpendicular to the first surface 10c, and the first air outlet 13 is formed between the first air outlet wall 131 and the second air outlet wall 132. The included angle between the first air outlet wall 131 and the first surface 10c is α1, and the included angle between the second air outlet wall 132 and the first surface 10c is α2, wherein α1≠α2.

[0091] By differentiating the included angles α1 and α2 of the first air outlet wall 131 and the second air outlet wall 132 as described above, the range of air outlet angle adaptability of the first air outlet 13 can be increased. Moreover, the first air outlet wall 131 and the second air outlet wall 132 can form a gradually converging first air outlet 13 or a gradually expanding first air outlet 13, so that the first air outlet 13 has different air outlet performance.

[0092] For example, when the required air supply distance increases, the first air outlet wall 131 and the second air outlet wall 132 can form a gradually narrowing first air outlet 13. When the required air supply range increases, the first air outlet wall 131 and the second air outlet wall 132 can form a gradually narrowing first air outlet 13 or a gradually expanding first air outlet 13.

[0093] Combination Figure 5 As shown, in some possible embodiments, the first air outlet wall 131 is located on the side of the second air outlet wall 132 opposite to the first surface 10c, where α1 > α2. Thus, the first air outlet wall 131 and the second air outlet wall 132 can form a gradually converging first air outlet 13, increasing the air delivery distance of the first air outlet 13. Furthermore, by increasing the tilt angle of the first air outlet wall 131, the air outlet axis 13a of the first air outlet 13 can be finely adjusted towards the side where the second air outlet wall 132 is located.

[0094] Combination Figure 5 As shown, in some possible embodiments, the first air outlet wall 131 is located on the side of the second air outlet wall 132 that is away from the first surface 10c, and the value of α1 ranges from 30° to 35°, and the value of α2 ranges from 25° to 30°. When the included angles α1 and α2 of the first air outlet wall 131 and the second air outlet wall 132 satisfy the above-mentioned value ranges, the air outlet direction of the first air outlet 13 will not blow directly onto the door body or door seal structure, and it has good air delivery distance and air delivery range.

[0095] Combination Figure 1 and Figure 3 As shown, in some possible embodiments, there are multiple second air outlets 14, which are spaced apart on the first surface 10c of the air duct plate body 1.

[0096] The area of ​​the second air outlet 14 located in the middle of the first surface 10c is larger than the area of ​​the second air outlet 14 located at the edge of the first surface 10c.

[0097] In order to increase the air volume in the area corresponding to the first surface 10c of the air duct plate body 1, there are multiple second air outlets 14, which are arranged at intervals along the first surface 10c, so that the total air volume of the second air outlets 14 can be guaranteed.

[0098] Furthermore, in order to ensure sufficient airflow in the middle of the first surface 10c of the air duct plate body 1, the area of ​​the second air outlet 14 in the middle position is larger, and the area of ​​the second air outlet 14 at the edge position is smaller, so that the cold air output in the middle position of the first surface 10c is larger.

[0099] Combination Figure 3 As shown, in some possible implementations, the air duct includes a main air duct 121, at least one first branch air duct 122 and at least one second branch air duct 123.

[0100] The main air duct 121 extends along the first direction A. One end of the main air duct 121 facing the first side 10a is connected to the air inlet 11, and the other end of the main air duct 121 facing the second side 10b is connected to at least one first branch air duct 122. The at least one first branch air duct 122 is connected to at least one first air outlet 13. At least one second branch air duct 123 is connected between the two ends of the main air duct 121 and is connected to at least one second air outlet 14.

[0101] With the above arrangement, the cold air input from the air inlet 11 can enter different first branch air ducts 122 and second branch air ducts 123 along the main air duct 121. The cold air entering the first branch air duct 122 can be blown out through the first air outlet 13, and the cold air entering the second branch air duct 123 can be blown out through the second air outlet 14.

[0102] Combination Figure 3 As shown, in some possible implementations, when there are multiple first air outlets 13, the multiple first air outlets 13 are divided into two groups, and the two groups of first air outlets 13 are located on both sides of the main air duct 121 along the second direction B, and each group of first air outlets 13 is connected to the main air duct 121 through a first branch air duct 122.

[0103] With the above arrangement, the two sets of first air outlets 13 can be connected to the main air duct 121 through two first branch air ducts 122 respectively. Moreover, the two sets of first air outlets 13 are arranged on both sides of the main air duct 121 respectively, which can ensure that multiple first air outlets 13 are arranged at intervals along the second direction B, and also ensure that each set of first air outlets 13 can obtain sufficient air volume.

[0104] Combination Figure 3 As shown, in some possible implementations, when there are multiple second air outlets 14, the multiple second air outlets 14 are divided into at least two groups, and the at least two groups of first air outlets 13 are located on both sides of the main air duct 121 along the second direction B, and each group of second air outlets 14 is connected to the main air duct 121 through a second branch air duct 123.

[0105] With the above arrangement, the two sets of second air outlets 14 can be connected to the main air duct 121 through two second branch air ducts 123 respectively. Moreover, the two sets of second air outlets 14 are arranged on both sides of the main air duct 121 respectively, which can ensure that multiple second air outlets 14 are arranged at intervals along the second direction B, and also ensure that each set of second air outlets 14 can obtain sufficient air volume.

[0106] Combination Figure 3 As shown, in some possible embodiments, a diversion rib 124 is provided in the main air duct 121. The diversion rib 124 is arranged along the first direction A and located in the middle of the main air duct 121 along the second direction B.

[0107] In order to ensure that the cold air in the main air duct 121 can be evenly distributed to each first branch air duct 122 and each second branch air duct 123, a diversion rib 124 is arranged in the middle of the main air duct 121 along the second direction B to divide the cold air into two streams, and the two streams of cold air flow into the corresponding first branch air duct 122 and the corresponding second branch air duct 123 respectively.
